The longer sides of the rectangles should be the same value, so we can make the lower part of the equation equal to 18, which is 4.
We can even find the y value by making it equal to 10, which is 3.

Answer:

 x=4 that is Option 2 is correct.

Step-by-step explanation:

The given figure is rectangle and since the opposite sides of rectangle are equal

hence, 18=10+2x

After simplification so as to get the value of x we get:

18-10 =2x

8=2x

After further simplification we get:

x=4

Therefore, option 2 is correct.

The table shows a pattern of exponents.<br><br> What is the pattern as the exponents decrease?
Marrrta [24]

Answer:

Option C is correct.

Step-by-step explanation:

We need to find the pattern as the exponent decreases.

the first value in the table is 125.

if we divide 125 by 5 i.e 125/5 we get 25

the next value in the table is 25

if we divide 25 by 5 i.e 25/5 we get 5

the next value in the table is 5

if we divide 5 by 5 i.e 5/5 we get 1

the next value in the table is 1

if we divide 1 by 5 i.e 1/5 we get 1/5

the next value in the table is 1/5

if we divide 1/5 by 5 i.e 1/5*5 we get 1/25

the next value in the table is 1/25

So, the pattern is if we divide the previous value by 5 we get the next value in the table.

So, Option C is correct.

Steve studies math for 7/8 of an hour and history for 2/3 of an hour. How many hours did he study?
hoa [83]

Answer:

The answer is 1 13/24 hours or 1 hour, 32.5 minutes

Step-by-step explanation:

Find a common multiple of the denominators 3 and 8, which would be 24.  Convert the fractions:

7/8 x 3/3 = 21/24.

2/3 x 8/8 = 16/24

Add the two numerators = 37/24 or 1 13/24.  

1/24 of an hour is 2.5 minutes, so 13/24 is 32.5 minutes.

The answer is 1 13/24 hours or 1 hour, 32.5 minutes

I believe there are 70 students in the theater!

Step-by-step explanation:

In the ratio 2:3 going to 28:? there is a pattern. You multiply 2 by 14 to get to 28, so if you multiply 3 by 14 you get 42. Add 42 to 28 for the total amount of students in class!

Find the area of the triangle with the given measurements. Round the solution to the nearest hundredth if necessary. B = 107°, a
Archy [21]

Answer:    105.19 \text{ square cm}      

Step-by-step explanation:

Since, by the SAS formula of finding the area of triangle,

The area of triangle, A = \frac{1}{2}\times s_1\times s_2\times sin\theta

Where, s_1 and  s_2 are adjacent sides and \theta  is the included angle of these sides

Here, s_1=22 s_2=10

And, \theta=107^{\circ}

Thus, the area of the triangle ABC,

A = \frac{1}{2}\times 22\times 10\times sin (107)^{\circ}

A = 110\times 0.95630475596

A = 105.193523156\approx 105.19\text { square cm}

Therefore, Third Option is correct.
